Hi there. I would need the reference ranges of your laboratory to be able to interpret these results. Also keep in mind that the levels can change somewhat from day to day within the normal range, so changes such as the drop in TSH may not be significant and must be interpreted in light of the clinical situation. Because you are pregnant, your hormone levels are more susceptible to fluctuations and must be monitored. Your GP can do this for you. However, if you want a higher level of expertise in terms of assessing you for hypothyroidism and monitoring your hormone status throughout your pregnancy, seeing an endocrinologist would make sense. I would suggest you await the results of the thyroid antibody panel first and see what your GP says. If you are not satisfied with the explanation or plan going forward, see the specialist.
